In this way, the drive torque is introduced not only on the first driver but also on the at least one second driver in the coupling element.
  • the first driver of the coupling element is designed and / or arranged such that it rotates upon the action of the output side torque of one of the ends of the wrap spring relative to the cylinder member such that the wrap spring is tensioned against the cylinder member and so the output side torque locks. It is particularly preferred if the first driver is not moved directly against one of the ends of the wrap spring, but against a previously described, with the wrap spring end pressure piece that is formed, preferably contoured, that a uniform force in the wrap spring and so that the lowest possible bending moment results.
  • the invention also leads to a drive gear unit with a previously described gear unit and an electric motor.
  • the electric motor drives it directly or only indirectly, for example via a worm gear, the transmission element, which is designed as a gear on. Due to the provision of a designed according to the concept of the invention gear unit with a coupling element having at least two drivers, the service life of the entire drive gear unit is increased due to the resulting reduction in wear.
  • the drive gear unit in which the coupling element is connected to transmit torque to a driven gear. It is also an embodiment conceivable in which the coupling element is integrally formed with the output gear. Particularly in the case of the last-mentioned variant, the output gear formed in one piece with the coupling element is preferably a plastic injection-molded part.
  • Fig. 1 is a transmission unit 1 for an adjustment in a motor vehicle, in particular for a window lift drive, shown.
  • the transmission unit 1 comprises a gear element 2 designed as an obliquely toothed driven gear (spur gear) made of plastic. This is driven by an electric motor (not shown), for example as shown in FIG DE 10 2005 012 938 A1 shown, powered. From the transmission element 2, the drive torque is transmitted to a coupling element 3.
  • the coupling element 3 in turn is non-rotatably connected to an output element 4 (here: driven gear), via which the drive torque to an adjusting mechanism, for example to a cable drum, will pass.
  • driven gear output element 4
  • Both the gear element 2 and the coupling element 3 are rotatably mounted on a rotationally fixed bearing axis 5, wherein the bearing axis 5 is integrally formed with a holding body 6.
  • an annular lid member is fixed, which is a transmission element 2 receiving recess 8 in the holding body 6 closes.
  • the cover element 7 is surmounted in the axial direction both by the bearing axle 5 and by the driven gear 6.
  • the coupling element has an inner ring portion 9, which is directly connected to the output element 4. Of the ring portion 9 protrude in two opposite radial directions, a first driver 10 and a second driver 11 away.
  • the drivers 10, 11 cooperate with the transmission element 2 in such a way that the output torque is uniformly transmitted to the two carriers 10, 11 from the transmission element 2, which leads to a uniform loading of the coupling element 3 as a whole.
  • the first driver 10 additionally cooperates with a load torque lock, which ensures that if a driven-side torque is introduced from the output element 4 or the coupling element 3 forth in a load torque lock 12, the latter blocks this output-side torque.
  • the load torque lock 12 comprises a spirally arranged wrap spring 13 which encloses in this embodiment radially outward designed as a drum cylinder member 14 (outer cylinder member).
  • the inner diameter of the wrap spring 13 is (slightly) less than the outer diameter of the cylinder element 14.
  • the outer diameter of the cylinder element 14 is more than 2 cm.
  • the cylinder element 14 is designed as an inner cylinder element (hollow cylinder) and the wrap spring 13 bears against the inner circumference of a cylinder element 14 designed in this way.
  • Each of the ends 18, 19 is associated with a pressure piece 16, 17, wherein the pressure pieces 16, 17 formed from thermoplastic shells are spaced apart in the circumferential direction and receive the ends 18, 19 of the wrap spring 13 in a form-fitting manner.
  • the transmission element 2 has an outer guide contour 20 for the wrap spring 13, which prevents the wrap spring in a small angle range far radially from the cylinder element 14 lifts when from the first driver 10, in the circumferential direction between the two Pressure pieces 16, 17 or between the two ends 18, 19 is arranged, is pressed. Furthermore, it can be seen that the wrap spring 13 is arranged approximately in the region of half the radius of the transmission element 2. A small distance of the guide contour 20 to the outer diameter of the wrap 13 is important for a small angular play in the function.
  • the first driver 10 Since the first driver 10 has the task of transmitting the drive torque from the transmission element 1 to the output, or in the reverse direction from the output to the pressure pieces 16, 17 of the wrap spring 13, the choice of materials takes place mainly under strength aspects. This particular because the first driver 10 must transmit the complete blocking torque at standstill of the transmission unit 1. Particularly preferred is therefore an embodiment of the first driver 10, preferably also of the second driver 11, more preferably also of the annular portion 9 of the coupling element 3 made of a fiber-reinforced plastic and / or metal. Alternatively, the first driver 10, in particular also the second driver 11, can be formed significantly larger, in particular when the angular ranges of the transmission element 1 reaching inwardly up to the wrap spring 13 are correspondingly reduced. In such, not shown embodiment, the first driver 10, preferably also the at least second driver 11 must take over the guiding function of the wrap spring 13 radially outside.
  • the output torque is evenly distributed from the transmission element 1 on the driver 10, 11, so that a uniform torque input into the coupling element 3 and thus in the output gear 4 results.
  • the angular and gap dimensions are dimensioned such that an at least approximately uniform torque distribution results on the two drivers 10, 11.
  • a further second stop 28 which lies opposite the second stop 21 in the circumferential direction, comes to bear against a further second contact surface 29, which is arranged on a side of the second driver 11 spaced in the circumferential direction from the second contact surface 22.
  • another first stop 30, which limits the recess 15 at the opposite end of the first stop 24, comes to rest on a contact surface 31 of the right in the plane of the drawing pressure piece 17, which receives the end 19 of the wrap 13 in it.
  • the pressure piece 17 is pressed in the plane of the drawing to the left with its contact surface 32 against a further first contact surface 33 of the first driver 10.
  • the two first contact surfaces 27, 33 of the first driver seen in the circumferential direction are on opposite sides of the first driver 10.
  • the first driver 10 If the drive from the coupling element 3 forth in the counterclockwise direction, the first driver 10 is pressed with its first contact surface 27 against the opposite bearing surface 26 of the left in the drawing plane pressure piece 16, whereby this is moved with the end 18 of the wrap spring 13 in the circumferential direction to the left , As a result, the wrap spring 13 is also clamped about the cylinder element 14 - the output torque is thus blocked.
  • a minimum backlash of preferably less than 6 ° can be realized. This is particularly important in view of the realization of a pinch protection in a window lift drive, since the electric motor, not shown, should reverse as soon as possible after detecting a Einklemmfalles.
  • elastomeric material is to be used in the load torque lock 12 for damping reasons, an embodiment is preferred in which the elastomeric material is preferably (only) arranged in the torque transmission chain transmission element (2) pressure pieces (16, 17) so that the elastomer material is not under load in the case of blocking , As a result, the amount of elastomeric material used can be reduced and / or the elastomeric material can be made softer. It is also possible to use elastomeric material in the Torque transfer chain second follower (11) -Griebeelement (2) to use.
